Frigid Temperatures Grip the Region, But Milder Days Are Ahead

Sioux Lookout faces frigid temperatures with wind chills near -30°C today. A slow warm-up arrives by Sunday with snow on the way

Sioux Lookout starts the day in a deep freeze with temperatures sitting at -25.9°C as of 6:00 AM at the airport. Though the skies are mainly clear, the north wind at 5 km/h is enough to push the wind chill down to a bone-chilling -31°C. Humidity sits at 79%, and the barometric pressure is at 103.8 kPa and rising, signaling stable but cold conditions.

Today’s Forecast: Sunshine, But No Warmth

The sun may be shining, but don’t let it fool you—it’s still bitterly cold. Winds remain light at up to 15 km/h, but even that slight breeze will make it feel like -30°C this morning before “warming” to a mere -15°C wind chill in the afternoon. The high for the day is -10°C, and with a risk of frostbite, anyone stepping outside should be fully bundled up. The UV index is low at 2, but with all this snow, sunglasses might help with glare.

Tonight: Clear Skies, Even Colder Temps

The skies remain clear through the evening, but clouds creep in after midnight. Winds stay light at up to 15 km/h, but the temperature drops to a frigid -21°C. The wind chill will make it feel like -18°C in the evening before sinking to -28°C overnight, once again bringing a risk of frostbite.

What to Wear: Arctic Survival Mode

Sioux Lookout is locked in a deep freeze, so full winter gear is non-negotiable. A heavy-duty parka, thermal base layers, insulated gloves, a hat, and a scarf are must-haves. Frostbite can set in quickly at these temperatures, so cover all exposed skin. If you’re heading out, consider double-layering socks and wearing windproof outerwear to block out the cold.
